TOBERA DE INYECCION DE COMBUSTIBLE LIQUIDO PARA SUMINISTRAR COMBUSTIBLE LIQUIDO A UN MOTOR DE COMBUSTION INTERNA

摘要

A fuel injection nozzle includes a valve member axially movable in a bore. The bore is in part defined by a sleeve secured within a drilling. A space is defined between the end of the sleeve and the drilling and fuel under pressure is supplied to the space by means of a groove formed in the external surface of the sleeve. The sleeve serves to support the valve member for axial movement towards and away from a seating defined in the bore and fuel can flow from the space past the valve member and seating through an outlet when the valve member is lifted from the seating.
